How to Bleed Cooling System?

[Bondavi]

When on inclines my temp gauge jumps momentarily. I think I have air pockets in the upper manifold where the temp sensors sit. Whats a good way to bleed the cooling system of all air bubbles?

Thanks in advance!

I'm not a Mercedes mechanic or expert. In my experiance to "Bleed or Purge or Burp" a cooling system, First you must find the "Highest" point of "Flow" usually the upper radiator hose at the radiator. Losen the clamp (sometimes just doing that will releive the air) sometimes you must loosen the hose to get the air out. Good luck on your "Fix". Let us know how it went.

Just remove the temp sensors and fill this air packed if is there with cooling fluid or water.
Good luck.

The sistem is self bleeding.
Your problem is the sending unit.
